Why not cut down your existing FSB?
Steel Gas Blocks ONLY.
Clamp-On is best suited to Precision Rigs that dont see rapid fire or abuse.
Do not rely on set screws alone to secure a Gas Block, especially on a Full Auto. You want it Pinned.
I suggest a BCM or Geissele Gas Block. Geissele can be pinned without a Jig, BCM requires a Jig.
Why steel? What about titanium?
I should have elaborated more. I should have said no aluminum for a gas block.
Titanium is fine.
The problem with aluminum for a gas block is the rate of expansion when they heat up. They will heat up at a different rate than the barrel and leak gas. They are awful.
Do the gas tubes make a difference? Is a titanium tube worth $65? Or is there no difference?

No. Titanium is not a good application for a gas tube IMO. Stick with standard gas tubes.
Melonite tubes are available too, but they offer no measured improvement that I have observed.

Can anyone recommend a low profile gas block that is steel and pins on? I don't mind cutting my sight block and reusing it as it will be hidden by the free float anyway but if there is one out there for under $50, I just assume go that route. I am anxious to get a move on with my free float barrel installation.
You would be better served in the long run if you just cut down your present 'pinned' gas block. It's as good a gas block as you'll get, short of an adjustable one. The new gas block will likely have to be drilled and pinned on it's own, as most don't use the pin holes from an A2 front sight/gas block.Can anyone recommend a low profile gas block that is steel and pins on?
